Describing CO2-Absorbent Properties in AspenPlus
(Journal article; Peer reviewed, 2019)For the modelling of novel solvent systemsfor CO2-capture in AspenPlus®, data fitting of physical-chemical properties is needed. In this work the challenges and results are presented for fitting such experimental data for ... -
Description of Supercritical Water-Hydrocarbon Systems
(Dr. ingeniøravhandling, 0809-103X; 2001:53, Doctoral thesis, 2001)Water +n-alkane systems at high pressures and temperatures, including the critical region, have been studied and modeled. All fluids exhibit fascinating behaviour near the critical point. Thus, the thesis begins with a ... -

Design and operation of water-wash sections to minimize MEA emissions
(Journal article, 2022)Whether in gaseous or aerosol form, mitigation of emissions from absorption-based carbon capture remains a real challenge. Among the available control technologies, water-wash is one of the most conventional and has been ... -
Design and setup optimization of ex-situ catalytic up-gradation of renewable biomass into fuel range hydrocarbons
(Master thesis, 2020)De raskt utarmende fossile brennstoffreservene og miljøpåvirkningen banet banen for alternative fornybare ressurser. Biodrivstoff skildrer en attraktiv mulighet til å erstatte konvensjonelle fossile brensler. Dette fører ... -
Design and simulation of dividing wall column for ternary heterogeneous distillation
(Master thesis, 2014)Heterogeneous azeotropic distillation is routinely used in chemical industry to separate close boiling point mixtures and azeotropes, which are not easily separated in a normal distillation process. Dividing wall column ... -
Design configurations of the methanol synthesis loop
(Master thesis, 2011)In recent years the chemical industry has undergone considerable changes due to increased environmental regulations and energy costs. This master thesis has evaluated three different design considerations of the methanol ... -
Design of plantwide control systems with focus on maximizing throughput
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:42, Doctoral thesis, 2009)This thesis discusses plantwide control configuration with focus on maximizing throughput. The most important plantwide control issue is to maintain the mass balances in the plant. The inventory control system must ... -
Designing monovalent selective anion exchange membranes for the simultaneous separation of chloride and fluoride from sulfate in an equimolar ternary mixture
(Peer reviewed; Journal article, 2022)Selective removal of multiple counter-ions in a single mixture is highly desirable for many industrial applications but also very challenging. This study focuses on designing monovalent selective anion exchange membranes ... -
Designing neural network control policies under parametric uncertainty: A Koopman operator approach
(Peer reviewed; Journal article, 2022)Solving the optimisation problem associated with nonlinear model predictive control (MPC) on-line when considering uncertainty is often infeasible due to the large computational times. One approach is to avoid the online ... -
Designing packed multi-partition wall dividing wall columns

Destabilization of crude oil emulsions by combining chemicals and electric fields
(Master thesis, 2015)In today s oil industry the increasing scarcity of the conventional oil is inevitable and pushes the oil companies towards the exploitation of unconventional oils such as oil- sands, heavy oil and extra heavy oil. During ... -
Destabilization of Emulsions in Porous Media
(Master thesis, 2016)Oil and water can form emulsions with different stability conditions while flowing through the porous systems in an oil reservoir. The stability of different oil-in-water (o/w), water-in-oil (w/o), and oil-in-water-in-oil ... -
Destruction of nitrosoamines with UV-light
(Journal article; Peer reviewed, 2013)In this paper the destruction of nitrosamines (NDMA and NDELA) in 30wt% MEA, 50wt% DEA and water wash solutions with UV-irradiation are presented and linked to measured penetration depths of UV- light. The results show ... -
Determination of apparent diffusion coefficient in balls made from haddock mince during brining
(Journal article, 2016)Salting is one of the main processes of preservation in meat and fish industry. Knowledge of how salt affects the muscle microstructure is needed both to model diffusion and to obtain the desired salt concentration in the ... -
Determination of Breakage Parameters in Turbulent Fluid-Fluid Breakage
(Journal article; Peer reviewed, 2019)Numerous sets of single‐particle breakage experiments are required in order to provide a sufficient database for improving the modeling of fluid particle breakage mechanisms. This work focuses on the interpretation of the ... -
Determination of kinetics of CO2 absorption in unloaded and loaded DEEA+MAPA blend
(Journal article; Peer reviewed, 2017)Alkanolamine blends are of high interest as solvents to enhance the CO2 capture technology in comparison to the traditional 5 M MEA. In the present work, the mass transfer and kinetics coefficients of the unloaded and ... -
Determination of Mass of Tetrameric Acid at the Air/Water Interface by Combining Langmuir-Schaefer with QCM Measurements
(Master thesis, 2013)Tetra-acid (also known as Arn) is a molecule present in petroleum crude oil at low concentration, typically the ppm level, which can precipitate in presence of calcium to form deposits. These deposits have an impact on oil ... -
Determination of the mechanism of the reaction between CO2 and alkanolamines.
(Master thesis, 2013)Emission control of greenhouse gases especially CO2 has become an environmental challenge. CO2 capture by absorption in amine is so far the only CCS technique that has been industrially acknowledged. Chemical absorption ...
